Abstract

I describe the advantage of using singular value decomposition as a diagnostic tool for exploring the potential and limitations of seismic data. Using stellar models coupled with the expected errors in seismic and complementary data we can predict the precision in the stellar parameters. This in turn allows us to quantify if and to what extent we can distinguish between various descriptions of the interior physical processes. This method can be applied to a wide range of astrophysical problems, and here I present one such example which shows that the convective core overshoot parameter can be constrained with one identified mode if the pulsating component is in an eclipsing binary system.
